What is the equation of the line through (-2, 5) and (0, 3)? A. y = x - 3 B. y=x+3 C. y = -x + 3 D. y=-x-3​

Answers

Answer 1

Answer:

C

Step-by-step explanation:

a typical line equation is the slope-intercept form

y = ax + b

"a" is the slope (always the factor of x) expressed as ratio of "y coordinate difference" / "x coordinate difference".

b is the y-intercept (the y value when x = 0).

going from (-2, 5) to (0, 3) we see

x changes by +2 (from -2 to 0).

y changes by -2 (from 5 to 3).

so the slope is -2/+2 = -1

using one of the points (0, 3) to solve for the missing b :

3 = -1×0 + b

b = 3

so, the equation is

y = -x + 3

A binomial experiment with probability of success p=0.63 and n=11 trials is conducted. What is the probability that the experiment results in 10 or more successes? Do not round your intermediate computations, and round your answer to three decimal places (if necessary consulta list of formes.)

Answers

To find the probability of getting 10 or more successes in a binomial experiment with p = 0.63 and n = 11 trials, we can use the cumulative probability function.

P(X ≥ 10) = 1 - P(X < 10)

Using a binomial probability formula, we can calculate the probability of getting exactly k successes:

P(X = k) = C(n, k) * p^k * (1 - p)^(n - k)

where C(n, k) represents the binomial coefficient.

Let's calculate the probability for each value from 0 to 9 and subtract it from 1 to get the probability of 10 or more successes:

P(X < 10) = P(X = 0) + P(X = 1) + P(X = 2) + ... + P(X = 9)

P(X < 10) = Σ[C(11, k) * p^k * (1 - p)^(11 - k)] for k = 0 to 9

Using this formula, we can calculate the probability:

P(X < 10) ≈ 0.121

Therefore, the probability of getting 10 or more successes in the binomial experiment is:

P(X ≥ 10) ≈ 1 - P(X < 10) ≈ 1 - 0.121 ≈ 0.879

Rounding to three decimal places, the probability is approximately 0.879.

A waiter earns tips that have a mean of 7 dollars and a standard deviation of 2 dollars. Assume that he collects 30 tips in a day, and each tip is given independently.a) Find the expected average amount of his tips.b) Find the standard deviation for the average amount of his tips.c) Find the approximate probability that the average amount of his tips is less than 6 dollars. Express your answer accurate to three decimal places.

Answers

Main Answer:The approximate probability is 0.033

Supporting Question and Answer:

How do we calculate the expected average and standard deviation for a sample?

To calculate the expected average and standard deviation for a sample, we need to consider the characteristics of the population and the sample size.

Body of the Solution:

a) To find the expected average amount of the waiter's tips, we can use the fact that the mean of the sample means is equal to the population mean. Since the mean of the tips is given as 7 dollars, the expected average amount of his tips is also 7 dollars.

b) The standard deviation for the average amount of the waiter's tips, also known as the standard error of the mean, can be calculated using the formula:

Standard deviation of the sample means

= (Standard deviation of the population) / sqrt(sample size)

In this case, the standard deviation of the population is given as 2 dollars, and the sample size is 30. Plugging these values into the formula, we have:

Standard deviation of the sample means = 2 / sqrt(30) ≈ 0.365

Therefore, the standard deviation for the average amount of the waiter's tips is approximately 0.365 dollars.

c) To find the approximate probability that the average amount of the waiter's tips is less than 6 dollars, we can use the Central Limit Theorem, which states that for a large sample size, the distribution of sample means will be approximately normal regardless of the shape of the population distribution.

Since the sample size is 30, which is considered relatively large, we can approximate the distribution of the sample means to be normal.

To calculate the probability, we need to standardize the value 6 using the formula:

Z = (X - μ) / (σ / sqrt(n))

where X is the value we want to standardize, μ is the population mean, σ is the population standard deviation, and n is the sample size.

Plugging in the values, we have:

Z = (6 - 7) / (2 / sqrt(30)) ≈ -1825

Using a standard normal distribution table or a calculator, we can find the probability associated with this z-score. The approximate probability that the average amount of the waiter's tips is less than 6 dollars is approximately 0.033.

Final Answer:Therefore, the approximate probability is 0.033, accurate to three decimal places.

large package. Let x be the number of small packages and y be the number of

large packages in the truck. What is the maximum revenue per truck?

Answers

Answer:

$680

Step-by-step explanation:

Capacity of the truck: 4200 pounds and 480 cubic feet of cargo.

Small package: 25 pounds and 3 cubic feet each.

Large package: 50 pounds and 5 cubic feet each.

For x number of small packages:

25x pounds and 3x cubic feet

Let x = 8,

200 pounds and 24 cubic feet.

For y number of large packages:

50y pounds and 5y cubic feet

Let y = 80,

4000 pounds and 400 cubic feet.

Since delivery service charges $5 for each small package and $8 for each large package.

The maximum revenue per truck = ($5x + $8y)

                                                       = ( $5 x 8) + ($8 x 80)

The range of y = - 32x ^ 2 + 90x + 3

Answers

Given:

The given function is:

\(y=-32x^2+90x+3\)

To find:

The range of the given function.

Solution:

We have,

\(y=-32x^2+90x+3\)

It is a quadratic function because the highest power of the variable x is 2.

Here, the leading coefficient is -32 which is negative. So, the graph of the given function is a downward parabola.

If a quadratic function is \(f(x)=ax^2+bx+c\), then the vertex of the quadratic function is:

\(Vertex=\left(\dfrac{-b}{2a},f(\dfrac{-b}{2a})\right)\)

In the given function, \(a=-32,b=90,c=3\).

\(\dfrac{-b}{2a}=\dfrac{-90}{2(-32)}\)

\(\dfrac{-b}{2a}=\dfrac{-90}{-64}\)

\(\dfrac{-b}{2a}=\dfrac{45}{32}\)

The value of the given function at \(x=\dfrac{45}{32}\) is:

\(y=-32(\dfrac{45}{32})^2+90(\dfrac{45}{32})+3\)

\(y=\dfrac{2121}{32}\)

The vertex of the given downward parabola is \(\left(\dfrac{45}{32},\dfrac{2121}{32}\right)\). It means the maximum value of the function is \(y=\dfrac{2121}{32}\). So,

\(Range=\left\{y|y\leq \dfrac{2121}{32}\right\}\)

\(Range=\left(-\infty, \dfrac{2121}{32}\right ]\)

Therefore, the range of the given function is \(\left (-\infty, \dfrac{2121}{32}\right ]\).

In a certain triangle, the measure of angle A is three times as big as the measure of angle C and the measure of angle B is 30 degrees bigger than the measure of angle C. What is the degree measure of angle A​

Answers

The degree measure of angle A is 90 degrees if the measure of angle A is three times as big as the measure of angle C and the measure of angle B is 30 degrees bigger than the measure of angle C.

Let x be the measure of angle C in degrees.

According to the problem statement, angle A is three times as big as angle C, measuring 3x degrees.

Angle B is 30 degrees bigger than angle C, so its measure is x + 30 degrees.

The sum of the measures of the angles in a triangle is always 180 degrees so that we can write:

A + B + C = 180

Substituting the expressions we found for the angles in terms of x, we get:

3x + (x + 30) + x = 180

Simplifying and solving for x, we get:

5x + 30 = 180

5x = 150

x = 30

Therefore, angle C has a measure of 30 degrees, angle B has an estimate of 30 + 30 = 60 degrees, and angle A has a measure of 3(30) = 90 degrees.

So the degree measure of angle A is 90 degrees.

a rotating light is located 12 feet from a wall. the light completes one rotation every 2 seconds. find the rate at which the light projected onto the wall is moving along the wall when the light's angle is 20 degrees from perpendicular to the wall.

Answers

The rate at which the light's projection moves along the wall when the light's angle is 20 degrees from perpendicular to the wall is approximately 1.078 feet per second.

Let's let t be the time elapsed since the light started rotating, and θ be the angle that the light makes with the perpendicular to the wall, as shown in the diagram. The rate at which the light's projection moves along the wall is given by the derivative of the horizontal distance between the projection point P and the foot of perpendicular Q, with respect to time t. Let's call this distance x.

From the diagram, we can see that:

tan(θ) = x / 12

Differentiating both sides with respect to time t, we get:

sec²(θ) dθ/dt = (dx/dt) / 12

We are given that the light completes one rotation every 2 seconds, which means that the angular velocity of the light is:

dθ/dt = 2π / (2 seconds) = π radians per second

Substituting this value and θ = 20° (converted to radians), we get:

sec²(20°) (π rad/sec) = (dx/dt) / 12

Simplifying:

(1/cos²(20°)) (π/2) = (dx/dt) / 12

Multiplying both sides by 12 and evaluating the left-hand side, we get:

dx/dt = 1.078 feet per second

As a result, when the light's angle is 20 degrees from perpendicular to the wall, the pace at which the projection advances along the wall is roughly 1.078 feet per second.

By using the method of reduction of order as in differential equation to find a second linearly independent solution of the: Equation x2y" + xy' – 9y = 0 (x > 0); yı(x) = x3 has general solution is y(x) = c1x^3 + c2x^(-2),

Equation  4y" – 4y' + y = 0; yı(x) = ex/2 general solution is y(x) = c1exp(x/2) + c2*exp(-x/2),

Equation x2y" – x(x + 2)y' + (x + 2)y = 0 (x > 0); yı(x) = x has general solution  y2(x) = (C3x^(3/2) + C4)e^(-x).

Equation (x + 1)y" - (x + 2)y' + y = 0 (x > -1); yı(x) = ex has the general solution y(x) = c1ex + [c2 - ln(|2x + 1|)/2]ex.

Using the method of reduction of order, assume a second solution of the form y2(x) = u(x)y1(x). Then we have:

y'1(x)u(x) + y1(x)u'(x) = 0

u'(x) = -y'1(x)u(x)/y1(x)

Integrating both sides:

ln|u(x)| = -ln|y1(x)| + C

u(x) = K/x^3

Plugging this into the differential equation:

x^2y'' + xy' - 9y = 0

x^2[u''(x)y1(x) + 2u'(x)y1'(x) + u(x)y1''(x)] + x[u'(x)y1(x) + u(x)y1'(x)] - 9u(x)y1(x) = 0

Simplifying and dividing by x^2y1(x):

u''(x) - 6/x^2 u(x) = 0

Equation r(r-1) - 6 = 0, which has roots r = 3 and r = -2. Therefore, the general solution is y(x) = c1x^3 + c2x^(-2).

Using the method of reduction of order, assume a second solution of the form y2(x) = u(x)y1(x). Then we have:

y'1(x)u(x) + y1(x)u'(x) = 0

u'(x) = -y'1(x)u(x)/y1(x)

Integrating both sides:

ln|u(x)| = -2ln|y1(x)| + C

u(x) = Kexp(-x/2)

Plugging this into the differential equation:

4y'' - 4y' + y = 0

4[u''(x)y1(x) + 2u'(x)y1'(x) + u(x)y1''(x)] - 4[u'(x)y1(x) + u(x)y1'(x)] + u(x)y1(x) = 0

Simplifying and dividing by 4y1(x):

u''(x) - u(x)/4 = 0

equation r^2 - 1/4 = 0, has roots r = 1/2 and r = -1/2. Therefore, the general solution is y(x) = c1exp(x/2) + c2*exp(-x/2).

Let y2(x) = v(x)y1(x), where v(x) is a function to be determined.

Then, y'2(x) = v'(x)y1(x) + v(x)y'1(x) and y"2(x) = v"(x)y1(x) + 2v'(x)y'1(x) + v(x)y"1(x).

Substituting y1(x) and y2(x) into the given differential equation, we get:

x^2(v"(x)y1(x) + 2v'(x)y'1(x) + v(x)y"1(x)) - x(x+2)(v'(x)y1(x) + v(x)y'1(x)) + (x+2)v(x)y1(x) = 0

Simplifying and dividing by x^2y1(x), we obtain:

v"(x) + (2/x - (x+2)/x^2)v'(x) + ((x+2)/x^2 - 1/x^2)v(x) = 0

Let u(x) = v'(x). Then, the above equation can be written as a first-order linear differential equation:

u'(x) + (2/x - (x+2)/x^2)u(x) + ((x+2)/x^2 - 1/x^2)v(x) = 0

Using an integrating factor of exp(∫[(2/x - (x+2)/x^2)dx]), we get:

u(x)/x^2 = C1 + C2∫exp(-2lnx)exp((x+2)/x)dx

u(x)/x^2 = C1 + C2/x^2e^(x+2)

v(x) = C3x^(1/2)e^(-x) + C4x^(-3/2)e^(-x)

Therefore, the second linearly independent solution is:

y2(x) = (C3x^(3/2) + C4)e^(-x)

41. (x + 1)y" - (x + 2)y' + y = 0, one solution y1(x) = ex.

We assume that the second solution has the form y2(x) = v(x)ex.

We can then find y2'(x) and y2''(x) as follows:

y2'(x) = v'(x)ex + v(x)ex

y2''(x) = v''(x)ex + 2v'(x)ex + v(x)ex

We can substitute y1(x) and y2(x) into the differential equation and simplify using the above expressions for y2'(x) and y2''(x):

(x + 1)[v''(x)ex + 2v'(x)ex + v(x)ex] - (x + 2)[v'(x)ex + v(x)ex] + v(x)ex = 0

Simplifying and dividing by ex, we get:

xv''(x) + (2x + 1)v'(x) = 0

This is a first-order linear differential equation, which we can solve using separation of variables:

v'(x) = -1/(2x + 1) dv/dx

Integrating both sides

v(x) = C1 - ln(|2x + 1|)/2

where C1 is a constant of integration.

Therefore, the second linearly independent solution is:

y2(x) = v(x)ex = [C1 - ln(|2x + 1|)/2]ex

So, the general solution is:

y(x) = c1ex + [c2 - ln(|2x + 1|)/2]ex

where c1 and c2 are constants of integration.

angels has a collection of nickels and quarters worth 8.80. if she has 68 nickels and quarters, how many quarters does she have?

Answers

Answer:

She has 27 quarters

Step-by-step explanation:

Let:

x = Number of nickels

y = Number of quarters

US$0.05 = 5 cents = monetary value of a nickel

US$0.25 = 25 cents = monetary value of a quarter

                      x + y = 68

                     x = 68 - y  ---- --------  (equation i)

                0.05x + 0.25y = 8.80----- (equation ii)

These two are linear simultaneous equations, which can be solved either by substitution, elimination or graphical method.

Substitution method:

Substitute (equation i) into (equation ii) to solve for y:

0.05(68 - y) + 0.25y = 8.80

Expand the brackets by applying the Distributive Law and then bring all the like terms together. y needs to be isolated and made the subject of the equation:

= 3.4 - 0.05y + 0.25y = 8.80

= 0.25y - 0.05y = 8.80 - 3.40

= 0.20y = 5.40

= y = \(\frac{5.40}{0.20}\)

y = number of quarters = 27

Let N = {0, 1, 2, 3, . . .}. Let be the subset of N × N defined as follows:
(i) (0, 0) ∈ .
(ii) If (m, ) ∈ , then (m, + 1) ∈ , (m + 1, + 1) ∈ , and (m + 2, + 1) ∈ .
(a) List nine elements of following (0, 0).
(b) True or false: if (m, ) ∈ then m ≤ 2. Prove your answer

Answers

(a) The Nine elements following (0, 0) are: (0, 1), (1, 1), (2, 1), (3, 1), (1, 2), (2, 2), (3, 2), (2, 3), and (3, 3).

(b) False; a counterexample is (2,3) which is in the set but violates the claim that m ≤ 2 for all (m, ) ∈ .

(a) The nine elements following (0, 0) in are:

(0, 1), (1, 1), (2, 1), (3, 1), (1, 2), (2, 2), (3, 2), (2, 3), (3, 3).

To see why, we use the definition of as given in (ii): starting with (0, 0), we can add (0, 1), then (1, 1) and (2, 1), which gives us three elements in the first row.

Then we can add (1, 2), (2, 2), and (3, 2) to get three more elements in the second row.

Finally, we add (2, 3) and (3, 3) to get the two elements in the third row, for a total of nine elements.

(b) False.

To see why, consider the element (2, 3). By definition (ii), if (m, ) ∈ , then (m + 2, + 1) ∈ .

So if (2, ) ∈ , then (4, 4) ∈ , which means that (4, 3) and (3, 4) must also be in .

But (3, 4) cannot be in , because it violates the condition that the second coordinate is at most one more than the first.

Therefore, (2, ) is not in , and we have a counterexample to the claim that m ≤ 2 for all (m, ) ∈ .

In fact, we can explicitly construct elements of for any m and : starting with (m, ), we add (m, + 1), then (m + 1, + 1) and (m + 2, + 1), and so on, until we reach a point where the second coordinate is too large to satisfy the condition.

This shows that there are infinitely many elements of with any given value of m.

True.
For any element (m, n) in the subset , we know that m and n are both natural numbers (elements of N).
Let's assume that (m, ) ∈  such that m > 2.
Then, we can say that there are at least three elements in N (0, 1, and 2) that are less than or equal to m.
Since  is a subset of N × N, this means that there are at least three ordered pairs (i, j) in  such that i ≤ m.
However, we know that  only contains ordered pairs where the second element is 9.
This contradicts our assumption that (m, ) ∈ , since we cannot have any ordered pairs in  such that the first element is greater than 2.
Therefore, we can conclude that if (m, ) ∈ , then m ≤ 2.
Hi! Your question seems to be missing some crucial information, but I'll do my best to explain the concept of subsets and elements using the number nine.

A subset is a set that contains some or all elements of another set, without any additional elements. In the context of the set N = {0, 1, 2, 3, ...}, a subset could be any collection of these elements.

Elements are the individual members within a set. In set N, elements include 0, 1, 2, 3, and so on. The number nine is also an element of the set N.

For the true or false statement you provided, it appears to be incomplete. If you can provide the complete statement or question, I'd be happy to help you further.

3. Suppose Mark has the following utility function: U(x,y)=min{2x,3y}. a. What is the utility of bundle (4,6) ? What is the utility of bundle (4,8) ? b. Draw the indifference curve that passes through the bundle (4,8). 4. Suppose Rob has the following utility function: U(x,y)=3x+2y. a. What is the utility of bundle (3,4) ? b. Draw the indifference curve that passes through the bundle (3,4).

Answers

The utility of bundle (4,6) for Mark, given the utility function U(x,y) = min{2x, 3y}, is 12.

the utility of bundle (4,8) for Mark is also 12.

For Rob's utility function U(x,y) = 3x + 2y, the utility of bundle (3,4) is 17.

The utility of bundle (4,6) for Mark, given the utility function U(x,y) = min{2x, 3y}, is 12. The utility is determined by taking the minimum value between 2 times the quantity of good x (2x) and 3 times the quantity of good y (3y). In this case, 2 times 4 is 8, and 3 times 6 is 18. Since the minimum value is 8, the utility of bundle (4,6) is 8.

Similarly, the utility of bundle (4,8) for Mark is 12. Again, we compare 2 times 4 (8) with 3 times 8 (24). The minimum value is 8, resulting in a utility of 8 for the bundle (4,8).

For the second part of the question, we'll now consider Rob's utility function: U(x,y) = 3x + 2y. The utility of bundle (3,4) for Rob can be calculated as follows: 3 times 3 (9) plus 2 times 4 (8), which equals 17. Therefore, the utility of bundle (3,4) for Rob is 17.

Indifference curves represent combinations of goods that yield the same level of utility for an individual. Since the utility function U(x,y) = 3x + 2y is a linear function, the indifference curve passing through the bundle (3,4) will be a straight line with a negative slope.

It implies that as one good increases, the other must decrease in a specific ratio to maintain the same level of utility. By plotting different bundles that yield the same utility level of 17, we can draw the indifference curve through the point (3,4).

The recursive formula that represents the value of account is a (n) = 1.0194 ;a (n-1); V (0) = 3.38.

What is meant by recursive formula?

Any term of a series can be defined by its preceding term in a recursive formula (s).

What is the general formula to find recursion?

The general formula to find recursion is \(a_{n}= ra_{n-1}\) where r is the common ratio and n should ne grater than 2.

a (n) = 3.38. a (n-1);a (1) = 1.0194

a(n) = 3.38. a (n - 1);a (0) = 1.0194

a(n) = 1.0194. a (n-1);a (1) = 3.38

a (n) = 1.0194 .a (n-1); a (0) = 3.38
